Get the fuck-butter mug.
Fuck butter is the creamy substance found concentrated at the base of the penis, dripping down the scrotum, on the lips of the vagina and always all over the sheets. Primarily, this is "churned" pussy juice that has been scraped from the cock each time it is plunged into the depths.

Fuck butter can sometimes be pink or streaked with pink if the vagina was injured during sex or if the female is ragging.

Also, fuck butter can be green. This is a sign of one fuct up piece of meat, either on the male or female side of the equation. Seek medical attention ASAP!
